Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 2 generators on 21 points:

(1,2,3,5,4)(6,8,10,16)(7,11,13,19)(9,15,18,21)(12,14,17,20);(2,3,4,5)(6,7)(8,14)(9,17,18,12)(10,13)(11,15,19,21)(16,20)

Polycyclic presentation:

2^6,5|a^2=c,b^2=f,b^a=bd,d^a=de,e^a=ef,g^a=g^2,c^b=ce,d^c=df,g^c=g^4
